Policy: Division Head Transfusion Medicine Role in Policy Making

drzeyd

Principle:

The Division Head, Transfusion Medicine and Blood Banks, is responsible for all aspects of transfusion medicine at HMC for the State of Qatar.  The following policy documents some of those roles.

Policy:

  1. The Division Head, Transfusion Medicine HTM, serves as a member of the Corporate Transfusion Committee
  2. The HTM through the CTC establishes criteria for transfusion of blood components and passes these through the HMC corporate process for establishing official guidelines.
  3. The HTM reviews blood component requests, especially in times of shortage to triage in conjunction with the Medical Director and Chairperson, DPLM
  4. The HTM establishes transfusion practices through the interim policies, which are in turn used to prepare processes and procedures through corporate transfusion medicine.
  5. The HTM serves as Project Manager for the Medinfo Hematos IIG computer system and prepares policies, processes, and procedures for Transfusion Laboratory Information Systems.

Building Donor Center Software Processes: Donor Physical Examination and Adverse Reactions

drzeyd

Donor physical examination, along with the donor questionnaire, are important both for donor and patient safety.  In general:

Is it safe for the donor to donate?

Is it safe for the patient to receive the blood even if it is safe for the donor to donate.

Any donor who does not feel well must not donate.  This may be the single most important step in ensuring a safe blood supply.

The donor physical examination includes the vital signs (blood pressure, pulse, temperature, heart rate, and temperature).  I have attached a sample set of criteria for review.  All are user-definable.  Note how the arm examination is also included (looking for scarring, skin lesions, etc.)

For all types of donations, there may be adverse reactions.  These must be documented in the record along with the disposition of the donation.  Will the donor need an extended deferral if the RBCs in the apheresis run are not returned?  This can be built from the reaction documentation.  Note the following sample table of reactions.

Building Donor Center Processes: Setting Deferral Intervals between Donation Types

drzeyd

Donation can be whole blood or apheresis-based.  The sex and age for each donation type is specified.  At HMC, we did not accept females for platelet or plasma donations, so the starting age is listed as 99 years.  Otherwise, in accordance with Qatari law, the starting age for donation is 18.  All these parameters are user-definable, and a transfusion medicine physician can override the rules if necessary.

For each and every combination of donations, the deferral interval must be specified.  Examples follow.  The temporary deferral period is in days:

Previous donation whole blood, current donation whole blood:  56

Previous donor platelets, current donation whole blood:  2

Previous donation whole blood, current donation platelets:  56

Also note how for each possible combination there is an entry for male AND female.  Females are restricted to whole blood donation and only RBCs will be made from the collection.

If there is a collection incident and the apheresis procedure is not completed, the interval will be set to 56 days.  This will be covered in the post on donor adverse effect reporting.

Building Donor Center Processes: Donation Type and Bag Parameters

drzeyd

At the time of registration, the type of donation must be specified.  In my last position, this could include whole blood for automated Reveos, whole blood for cryoprecipitate, plasmapheresis, COVID 19 convalescent plasmapheresis, plateletpheresis, concurrent platelet and plasmapheresis, concurrent platelet, plasma, and RBC apheresis, RBC apheresis-one unit, and RBC apheresis-2 units.

There is also a specimen-only donation without actual collection that includes database check, assignment of an ISBT specimen number, donor questionnaire, physical examination, and specimen collection only..

We specified which bag or kit could be used for each type of donation so when it was selected, only that bag type would be accepted by Medinfo

For each of these types we must specify what type of donation is permitted:  volunteer, autologous, or directed.

Finally, we must indicate the maximum length of the procedure permitted.  This applied to whole blood only and we set this at 15 minutes—this is user definable.

The following are a sample set of parameter settings for the above:

Note how we included contingencies for old bag sets and equipment (that we later discontinued) and for granulocyte collection (which we did not actually perform).
